MACHENE FOR THE MANUFACTURE OF DASHES.

SPECIFICATION forming part of Letters Patent No. 232,899, dated October5, 1880.

Application filed December 15,1879.

To all whom it may concern Be it known that we, GEORGE M. PETERS andALBERT STANDIsH, of the city of Columbus, county of Franklin, and Stateof Ohio, have invented certain new and useful Improvements in Machinesfor the Manufacture of Dashes and Fenders, of which the following is aspecification.

Our improvements relate to the manufacture of that class of dashes whichconsist of a frame covered with leather or other suitable material.

WVhen footless dashes or fenders, &c., are to be manufactured it isexceedingly advantageous to sew up the edges of the cover so that thelatter forms a bag, three sides or edges of which are closed and thefourth is opened. It then becomes necessary to insert the frame into thebag.

Our invention enables the cover to be readily and accurately set inproper and convenient position for the insertion therein of the frame,and to be firmly sustained while the frame is being inserted, and alsoenables the frame to be thoroughly driven into the cover, although thedepth of one side of the cover may be slightly greater than that of theother.

Our invention also enables the same ma chine to be conveniently andquickly adapted to covers of different widths, and thereby obviates thenecessity for the employment of as many different machines for insertingthe frame into the cover as there are covers of different widths.

In the accompanying drawings, Figure 1 represents a rear elevation ofour machine. Fig. 2 represents a sectional elevation of the machineshown inFig. 1, the section being taken at the line X X, Fig. 1. Fig. 3is a perspective View of one of the grasping-links.

The frame-work of the machine consists oftwo end supports, A A, havingsecured to them the two guide frames or bars B B by means of bolt 1),passing through feet 0 of the guide-frames and the upper flanges of theend supports, A A. The guide-frames B B have dovetailed projections b Onthe rear guide frame, B, are two standards, (J 0, one of which ismovable an d the other, preferably, inimovable. Each of these standardshas a dovetailed groove, which fits over the dovetailed projection b ofguide-frame B. The standards have a broad basilar portion, 02in which isplaced the groove which fits over the projection L The part of eachstandard above the portion O when contracted in width, as shown in Fig.1, is, preferably, provided with strengthening-braces 0 In the top ofeach standard is a slot, 0, in which is placed a sheave, 0 Over thissheave 0 passes a cord, O to the rear end of which is attached a weight,W, and to the front end a rack, D, whose teeth (I ei'igage with theteeth of pinion E. Back D is provided with a notch, d, in its lower end.WeightW and rack D counterbalance each other. Pinion E is keyed to shaftF, and is operated by suitable mechanism, as hand-whecl Gr, keyed to thesame shaft. Each rack D is directed by guides H, one or both of whichare provided with a cap, h, for the purpose of keeping the rack close tothe face of standard 0. On the front guide-frame, B, are two blocks orjaw-holders, I, each provided with a dovetailed groove fitting over thefront dovetailed projection, 11 of the frame. One of these blocks I isplaced directly opposite each of the standards O G, and moves or isstationary, according as the standard to which it is opposite moves oris stationary. As standard 0 is shown in the drawings as stationary andfixed, so the block opposite the standard 0 is fixed to the standard 0,and its blocks are each bolted in like manner. The block oppositestandard 0 is arranged to slide upon the front projection, if", of theframe as its opposite standard does upon the rear projection, 1)",thereof, the block and its standard being preferably so connected thatboth must slide together along the frame.

One of the clamping-jaws is shown in Fig. 3. It consists of ashank,'j,whose upper portion is provided with a curved lip, j. Theshankj fits into a recess in that side of the jaw-holder which is nextto the guide-frame.

A similar recess is cut in the lowest part of IOO 3o jection t'.

means, as connectingrod N. Each of the crank-arms M centers on arock-shaft, O, preferably polygonal in cross-section, one end of eachrock-shaft beingjournaled in the end supports, A and A, and the otherend of each of said rock-shafts being journaled in the center support,0. Attached at one end of each shaft 0 is its opcratin g foot-lever.This lever has a tooth, p, on its side, which engages with the teeth ofrack work p, thereby securing the lever in position.

A spring, Q, is stretched between the crosshead L and its respectivejaw-holder I on the one side, and a spring, Q, is stretched between eachcross-head and its respective standard, 0 or G, on the other side of theframe.

On the outer side of each guide-frame is a screw-threaded shaft, B. Thisshaft is supported by a journal-bearing, T, near one end, and the otherextremity may be free, having no bearing,orbe supported byitsbeingrounded smooth and fitting in a bearing similar to the first, or ina socket, as shown in Fig. 1. One shaft R passes through the portion ofstandard C and engages a female screw in said standard, and the shaft Ron the other side of the machine passes through the projection t' of theblock I on the rear side of the frame and engages a female screw in thesaid pro- One of the shafts R has a righthand screw-thread, while theother has a lefthand screw-thread. Each shaft R, near its outer end, hascentered on it a cog-wheel, S. These two cog-wheels S are preferably ofthe same diameter, and the same number of teeth gear together. One orboth of the shafts R are produced beyond the wheels S, and are fitted toand receive a suitable device, as a crankhandle, &c., for operating thesaid shafts.

The method of operation of our machine is briefly as follows: Thestandard C and opposite jaw are first regulated in their position on theguides B and B so that the jaws J will grasp the extremities of thedash-cover. Then the dash-cover, three of whose edges have been sewed,is lowered into the open space between the guide-frames B B, the openedge being uppermost. The lips of this open edge are now placed betweenthe lips j and the guide-frame on their respective sides, and thefoot-lever P depressed and secured in position a by the tooth 19engaging with the rack-workp. When both of the foot-levers I? have beendepressed and secured, the four jaws J securely hold the lips of thecover in the position in which they were placed. The frame of the dashis now inserted by hand into the cover as far as it will go.Thehand-wheels Gare now turned in the proper direction, forcing theracks downward. The notches d fit over the edge of the dash-frame, andthe racks descending force theframe home in the cover. If one end of thecover happens to hang lower than the other end, the rack on that sidemay be forced farther down, thus enabling the operator to always put theframe in the proper position in the cover. The foot-levers are nowreleased, and the springs Q retract and elevate the clamping-jaws, sothat the dash may be removed from the machine.

When very short dash-frames or frames for fenders are to be insertedinto a cover, it will only be necessary to use one pair of the jaws openedge is being sewed up, but little force being required to keep theframe home after the use of our invention.

As will be observed, our invention enables the cover to be held in avertical position for insertion of the dash-frame. The tendency of onelip of the cover to fall upon the other and retard the handling of saidlips and the insertion of the frame-a tendency ever present when thecover lies in a horizontal position-is entirely obviated by ourinvention. The latter enables the lips to be handled with ease anddispatch, and the frame to be easily, quickly, and correctly insertedinto the cover.

substantially as specified.
